Place a square block with a mass of 25kg and a side length of 10cm in the center of a horizontal table with an area of 1m2. What is the pressure of the block on the table? What is the pressure Pa? If the object is cut half in the vertical direction, what is the pressure of the remaining part on the table? (G is 10N / kg)

Place a square block with a mass of 25kg and a side length of 10cm in the center of a horizontal table with an area of 1m2. What is the pressure of the block on the table? What is the pressure Pa? If the object is cut half in the vertical direction, what is the pressure of the remaining part on the table? (G is 10N / kg)

The gravity g = mg = 25kg × 10N / kg = 250N,
Therefore, the pressure of the block on the desktop is f = g = 250 n
1 m × 0. 1 m = 0;
Therefore, the pressure of the block on the table is p = f / S = 250 n / 0.01 M & # 178; = 25000 PA
If the object is cut in half along the vertical direction, the pressure and the stressed area will be reduced by half, and the pressure will remain unchanged at 25000 PA
Note: the pressure is related to the contact area, but not to the actual area
